When they updated the CX-7 in the US, they added a GPS system and a backup camera which were now common, if not standard features, on most vehicles. That's why current models now have a color MID installed.
On the local models, the monochromatic MID cannot work as a display for the backup camera because of the type of screen and it's resolution (and refresh rates, if you want to be nerdy about it).
Having said that though, there are some options available online (I will only talk about original Mazda replacement parts as I am particular about keeping my CX-7 "stock").
1) You can order the backup camera and rearview mirror monitor kit. This is what's in Chapter 6 of your owner's manual. Basically, the camera is installed near the rear license plate, and your rearview mirror is replaced. There is a color monitor built-into but hidden inside on the left side of the rearview mirror. The monitor will only be visible when you set the vehicle to reverse (much like how a one way-mirror works).
2) You can order the backup camera separately. And then order the color MID and GPS kit. You will not be able to upgrade the GPS system to work here but you will be able to use the MID as a display for your backup camera. It may be closer to what you want but you will be paying extra for a feature you won't be able to use.
Hope this clarifies a few things.
